CONTROLLING MECHANISM FOR WORK-POSITIONING MEANS.

Patented Jan. 24, 1922.

Application filed March 17, 1919. Serial No. 283,149.

To ail whom it may concern:

Be it known that I, Ins. C. BUCKMINSEER, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Controlling Mechanism for Work-Positioning Means, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in he several iigures.

My invention relates to controlling mechanism for work-positioning means, as for the band-clamps which, in heel-attaching machines, correctly locate with relation to the nailing mechanism a lasted shoe supported upon a jaclcpost. These band-clamps are commonly joined to the j ack-post, as by a chain, for movement thereby, being lowered under the influence of gravity when the jack-post carrying the shoe to which the heel is to be attached is swung into the nailing position, and being elevated out of the path of the nail-transferring mechanism when the jack-post is oppositely moved for the reception of another piece of work. To correctly engage and position the shoe, the lower edge of the band is adapted to enter the rand-crease, and to permit this when the lasts vary in height, it is necessary for the o erator to alter the relation of the bandcamp to the jack-post, as by changing the effective length of the connecting chain.

The present invention has for an object the elimination of such a manual adjustment of a work-positioning member, and the provision of means whereby the band-clamp or other positioning means will be caused to engage the work properly when its dimensions vary.

As a feature of the invention, there is combined with a work-support and a'workpositioning member, novel means "for controlling said positioning memherin accord .set by said gage-plate, which stop the work-support, or jack-post. In the illustrated embodiment, the controlling memher, as well as the positioning member, is movable under the influence (it the worksupport, but preferably at a different rate therefrom and during at least a portion of its travel in the opposite direction. This permits 1t to be brought into engagement with and measure work of varying dimens 1ons. In so doing, it may set movement limiting means in advance of the positionmg member, thereby determining the extent of movement of the latter. In the illustrated heel-attaching machine, a'gage-plate actuated with the band-clamp by the jackpost 1s brought by a differential travel, produced by gearing in the connections. against the heel seat of whatever height of lasted shoe may be upon the jack-post, and a stop is ongaged by an element carried by the bandclamp.

To obtain the desired measuring effect. as another feature of the invention. 1 interpose the controlling member in a novel manner between the work-support and the means tor operating upon the work, and. to avoid intert'ernce with this operating means; the

. controlling means is movable out of the path of the support and operating means, it thus preferably having a movement toward and from the work-support to effect its measuring or stop-setting function. and a lateral movement with respect to the support to carry it clear of the operating means. The controlling means may have oo-operating with it, means, as' a spring, for forcing it toward one extreme of movement, it beingthere temporarily retained or latched at the opposite extreme, and, to shift the controlling means to its latched position, there is herein disclosed means under the influence or" the work. To release the controlling means, there is shown means under the joint infiuence of the work, the work-positioniug means and the controlling means itself. though thi action may be accomplished by tower ole ments. In a heel-attaching machine there may, as to this feature, be combined with nailing mechanism, a jack-post and a handclamp, a gage-plate or other controlling member movable between the nailing mechanism and jack-post, with spring exerting its force to move the plate toward these elements and a latch for retaining the plate clearthe'reof. There is an actuator for releasing the latch and also an actuator for setting the plate against the tension of the spring. A pawl is shown traveling with the gage-plate for engagement with teeth connected with the band-clamp. The engagement of the pawl with the teeth is governed by an ac under the influence of the work.

trolling means for the measuring means in its work-measuring relation Thisallows, for example, moving the controlhng means from between the work and mechanism opcrating thereon after the stop for the posiioning means has been set by contact of the controlling means with the work, without disturbing such setting. This retaining or locking of the controlling means may be through the instrumentality of a clutch, and, in the heel-attaching machine disclosed herein, 'co-operating clutch elements are carried by a supporting element and the gage and stop mechanism by which the band-clampis controlled. I p'refer to operate the clutch by movement of the jack-post and contact of the work thereon, the actuating means being shown as connected to the band-clamp.

Other features will be evident upon consideration of the following description illustrated by the accompanying drawings, in which r Fig. 1 'is a side elevation of'a portion of a heel-attaching machine including one eme'mbodiment of the invention, the jack-post being in its work-receiving position;

Fig. 6 shows co-operating elements of the clutchactuator separated from one another.

There appears at 10 the work-spindle of a heel-attaching machine, it being mounted for reciprocation in the usual manner and having fixed to its lower end 'a head 12. In ways in this head is adjustably mounted a slide 14. Between lugs 16 depending therefrom is pivoted a jack-post 18. When in its forward position, the j ack-post may have placed upon it a lasted shoe, indicated at S, the shoe and last together being considered for the purposes of the present invention to constitute the work operated upon. Atits other extreme of movement, as illustrated in Fig 2, the jack-post presents the shoe to nailing mechanism, of which a nail-block 20 and drivers 22 only are shown, these inserting the nails which attach the heel'H. To position the shoe correctly with relation to the heel held. over the nail-block, a bandclamp mechanism is provided, which generally does not differ essentially from what has been heretofore employed. I have shown a band 24, arranged to contact with the counter portion of the shoe upon opposite sides, the lower edge of the band entering the rand-crease, the engaged shoe thus being located both horizontally and vertically for the nailing operation. Theband is pivoted upon arms 26mounted for adjustment by screw 27 upon a transverse extension 28 at the lower extremity of a slide 30, this slide being vertically 'movable in a supporting and guiding member 32. The support 32 is adjustable by a screw 34 in a horizontal direction to determine the location of the-work transversely of the machine upon the lower end of a vertical arm 36,, the upper portion of which is movable on the slide '14, toward and from the jack-post to properly locate the work in this direction, by a screw 88 and clamped inits'adjusted position by a screw 40; The band-clamp, through the slide30, is joined in the customary manner to a hook42 projecting from the top of the jack-post by a chain 44 passing over a sprocket wheel 45 rotatable atthe rear of the slide 14. This connection causes the band-clamp to be raised above the'path of the nail-loading mechanism (not illustrated) when the'jack-post is in the inactive or work-receiving position illustrated in Fig. 1, and, to permit said band-clampto fall by gravity into the work-positioning relation shown in Fig. 2, whenthe jack-post is shifted to the operating or nailing position. The vertical relation of the band to the work, so that the lower edge may be alined with the rand-crease, is effected by hooking different links of the chain 44 upon the hook 42 or, more exactly, by turning a screw- 46 threaded into the top of the slide 30 and having a head resting upon a terminal 48 of the chain.

g It will be clear that. unless the connection between the j ack-postv and band-clamp is changed when the height of the last within the shoe applied to thejack-post varies, the lower edge of the band will be either above or below the rand-crease of the shoe, and the band will not properly engage and position the work. To overcome this difiiculty, my novel controlling mechanism is employed. In the bandclamp slide 30 is a. vertical way 50 for a sliding carrier member' '52, which bears a stop-"nember54 projecting through a vvertical slot 56 in the front of the slide 30. With this membep 54 a stop-projection 58 upon the slide 30 co-operates, there preferably being a screw threaded vertically through the projection 58 and serving to alter the point at which the stop arrests the movement of the band-clamp mechanism, and thus controls the relation of the band to the work for any particular adjustment of the band-clamp connections. The screw 60 may be fixed in its adjusted position by a set screw 62 threaded through the side of the projection 58. Motion is imparted to the slide 52 from the jack-post by a. chain 64 joined to an adjusting screw 66, operating similarly to the screw 46. This chain ca passes over a sprocket 68, mounted to turn independently beside the sprocket 45, and at its opposite or upper end is attached to an arm fixed to a shaft 72 rotatable in lugs 74 at the upper rear portion of the jack-post. Fast upon the shaft 72 is a pinion 7 6 meshing with a gear-segment 78 formed upon one of the lugs 16, this gearing causing the rotation of the arm 70 and the consequent raising or lowering of the con trolling slide 52 as the jack-post is oscillated. Included in the chain 64 is a spring 80, the purpose of which will later appear.

To determine the location of the sto 54 and, therefore, the extent of descent of the band-clamp in accordance with a characteristic of the work, in the present instance the height of the last or the distance of the heel seat portion from the surrace resting against the end of the jack-post, there is a page mechanism contacting with the work to measure it. At the bottom of the slide 52 are brackets 82, 82 spaced from one an other transversely of the machine, upon which brackets are pivoted, at 84-, horizontal gageplates 86, 86. Tension springs 88, extending between arms 89 of the plates and projections 91 from the lower end of the slide. exert their force to turn the plates toward one another about their pivots until flanges at their upper faces contact with or are adjacent to the sides of the band 24:. The setting action of this gage and stop mechanism is as follows: When the jack is in its work-receiving position (Fig. 1), the arm 2 0 connected to the chain of the slide 52 is substantially horizontal. As the jack-post moves inwardly toward the nailing position, the hook 42 rises and permits the bandclamp slide to fall by gravity at the same rate as the jack-post moves. Because, however, of the action of the gearing 76, 78, the arm 70 moves more rapidly than does the hook 4-2, its travel being first upward. The slide 52 carrying the gage plates 86 therere falls more rapidly than does the band clamp, traveling down the way 50, this con tint C until it has reached a position below the band 24 sufficient to provide for the measuring of the highest last which may be employee in the work. At this time, the arm 0 has reached its highest position and begins to, move to the left, as viewed in Figs. 1 and 2, now exerting a positive pull upon the chain 64-, and therefore raising the slide As the jaclepost has now carried the shoe over the plates 86, the upward movement of the slide brings them against the heel seat, this occurring before the jack-post is in its vertical position. Further movement of the arm 70 simply draws the plates 86.1nore firmly against the shoe, the spring 80 yielding to permit this. The stop is tons located by the gage-plates at a point determined by the height of the last. this having been accomplished before the jackpost reaches the operating position.

To free the heel seat of the shoe for the attachment of the heel, the plates are moved clear of the work and nailing mechanism, and this I prefer to bring about under the influence of the travel of the jack-post and work. Secured to the rear of the band 24 at 98 and guided. by a stem 92, which reciprocates in a guide sleeve 94: threaded into the slide 30. is an actuating member 96. This member has lateral arms 100, 100, from the outer extremities of which depend contact pins 102 through openings 10% in the plates 86. The pins rest against the edges of the openings which are curved at 196 to form cam surfaces. YVhen the shoe, in the rearward travel of the jack-post to the nailing position, contacts with the band-clamp. movingit inward, the member 96 is carried with it. and the pins 102. bearing upon the cam surfaces 106, turn the gage-plates 86 100 about their pivots so they are swung to opposite sides of the shoe and the nail-block. clearing the intermediate space for the nailing operation.

Having thus freed the work of the gageplates. it is desired to temporarily retain them in their inactive position for time independently of the pressure of the work upon the band. In a rearward extension 108 of each plate is an opening 110 for engage- 1 ment by a latch pin 112 movable vertically in a socket 114 formed upon the bottom of the slide 52. A spring 116, surrounding each latch pin within its socket. tends to force it downward so it may enter the corre- 115 sponding opening 110.

Fwince. after the plates pass from beneath the work, their location-determining effect upon the stop 54 is lost. it is necessary to first independently fir: the stop in its set position. For this purpose, the support 32 carries at its lower rear portion, in a casing 118. clutch members 120, shown as multiple plates mounted upon a stud 122 projecting band-clamp may be utilized. Uponthe rear extremity of the stem 92 is-a head 130, rectangular in form and best shown in Fig. 6 of the drawings, arranged to slide in a vertical way 132 in the trout face of a head 134 carried upon a stem 136. This last-morn tioned stem is guided for horizontal movement in a perforated boss 138 projecting from the outer face of a cover-plate 140' for the casing 118. The stem 13G moves between plates L12 depending from the stud 126 and has at one side, toward the clutch-plates 12S, cam surfaces 14%, which contact with oppositely inclined surfaces 1% upon one ot the plates 142. From this last-mentioned cam-plate, bosses 1 1-8 project toward the adjacent clutch-plate 128, and surrounding the bosses and contacting at their ends with the plates are springs 15(). hese springs, when the plate 142 is moved under the influence of the cam-surfaces, act to force the plates 128 into clutching engagement with the companion plates 120 and thus lock the slide 52 to the relatively fixed support 32. The camsurt'aces are sharply inclined, as a result of which, as soon as the contact 01? the work with the band 24- moves back the member 96 and its stem 92, the plate 142, through its bosses, produces engagement of the clutchplates, fixing the controlling slide with the stop in the position to which it has been adjusted by'the gage-plates, before these plates are moved by the pins 102 and cam surfaces 106 out of contact with the heel seat of the shoe. After the clutch has thus locked the gage and stop mechanism, inter terence with the final engagement of the bandwith the work, because the actuator sections 92 and 136 are fixed to the band-clamp and support, respectively, is avoided by the movement of the head 130 in the way 132.

After the completion of the nailing operation, the gage-plates must be released from their latches so that the sp ingsfitl may restore the plates to their normal position. This preferably takes place after the shoe operatednupon has reached a point in the forward movementot the jack-post beyond the gage-plates, so that, upon their release, the edges of the plates will not strike the up per of the shoe, thus avoiding the possibility of their marring it. To accomplish this'deferred release, I may employ the difi'erential movement between the slides 30 and 52. Pivoted to the latch pins 112 is a lever 152, tulcrumed at 154- upon the side of the slide 52. The lever is divided at 156 and between the arms is pivoted. a pawl 158 projecting upwardly through an opening 160 in the stem 92 of the actuating member 96. The pawl maybe moved into engagement with a vertical series of ratchet teeth 162,

carried upon the rear face of the bandclamp slide 30. After the nailing operation, when the heeled shoe is withdrawn from the band-clamp by tie 'forward movement of the jack-post, theband, traveling for a time with it in engagement with the shoe and acting through the member 96 and stem 92, turns the pawl 158 about its pivot until its upper end engages the ratchet teeth 162. During the earlier portion of the dif ferential movement of the slides 30 and 52, the latch pins 112, are unaffected, but when, after the shoe has passed beyond the ends or the plates 86 as'the slide- 52 moves up more quickly than does the slide 30, the fulcrum 154 of the lever 152 rises at a more 'apid rate than does therear end, held by the pawl. This swings the lever about its fulcrum, lifting the latch pins out of the openings 110 and releasing the gageplates 86, which are swung by their springs 83 to their normal positions, as illustrated in Figs. 3 and 4. In the reverse movement of the jack-post, when the extreme of t'rvel is nearly reached, the movement of the actuator 96 and stem 92 by the band-clamp under the influence ot the supported shoe, forces the forward edge of the stem opening 160 agalnst the pawl, releasing 1t from the ratchet teeth and allowing the springs 116 to force the pins into the openings 110. This release does not occur until the pins are above the surfaces of the plate arms 108, so they fall upon these and ride over them into the openings.

Theconiplete operation of the apparatus will only be generally outlined. The operator applies the jacked shoe to be heeled to the jack-post and swings it from the position of Fig. 1 to thatot' Fig. 2. The band clamp is allowed to fall toward its shoe-re-- ceiving position, while the gage and stop mechanism first falls more rapidly, to with certainty reach a'point below whatever shoe is to'be'operated upon, and then is drawn up into contact with its heel-seat. Toward the end of the movement of the jack-post and under the control of the actuator 96,

the stop mechanism is locked by the clutch- 7 plates, the gage-plates are forced clear of the work, and the latch pins are released and caused to retain the gage-plates in the posi' tion for the nailing operation. When the screw 60 contacts with the set projection 5-1, V

and tripping the latches tor the gage-plates, which are returned to thelr springs to position for another operation.
